AFAIK, Stillen was advising against the purchase of headers because they are unsure of yet if the loss in boost will = a loss in power as well, or a gain. With what we know of fitment and location of the SC, which is almost nothing, its also unknown at this time if headers (read: LTH) will be in the way. IMHO, I don't think it will present a problem and will more than likely drop boost, but there shouldn't be a power drop, but a gain.

On another note, losing boost doesn't always mean losing power. Boost is, in a way, a measurement of airflow. The more restricted the pathway the more boost at a given CFM; the less restrictive the less boost, but same CFM. Its entirely possible for 2 like engines to make the same power at different boost levels given one flows more freely than the other. An example is a friends STi; before full exhaust mods his turbo would peak at 20-22 psi, after it peaked at 18-20 psi, yet he gained a good 30 awhp.

If I am wrong in anything I have typed, I just made ***

Please correct if I am, my knowledge is limited.

+1 for hngonzalez!

That is basically correct.

I wouldn't worry about installing any type of header until we have a chance to test the results of the combination.

One thing to consider is that hi flow cats and headers and Cat-back exhaust plus intake leave the car running a bit lean. So, now delete the cats altogether and include the headers and no restriction or anything and you can pretty much guarantee that the long tube headers will cause the car to run a bit lean.

I would not install any headers from any company...STILLEN, Fast Intentions or any other until we have a chance to test and tune with them.
